Maybe they can be implemented like long double _gfortran_xyz (long double x) { __sorry_fortran_intrinsic_xyz_is_not_available_because_cosl_is_not (); } instead of simply not providing them. Coordination between the FE and (the various multilibs of) libgfortran and emitting diagnostics from the FE would of course be even better.
